BS EN 60297-3-100-2009 PDF

Full title and description

BS EN 60297-3-100:2009 — Mechanical structures for electronic equipment — Dimensions of mechanical structures of the 482,6 mm (19 in) series — Part 3‑100: Basic dimensions of front panels, subracks, chassis, racks and cabinets. This British adoption of the EN text is identical in scope to IEC 60297‑3‑100:2008 and establishes the basic dimensional interfaces (front panels, subracks, chassis, rack and cabinet mounting grids) used across the 19‑inch equipment family.

Abstract

Specifies the basic dimensions and mounting interface details for equipment constructed to the 482.6 mm (19 in) series: front panel heights and pitches (including the 1U = 44.45 mm convention), recommended mounting‑hole positions, rack/cabinet mounting grid types, and baseline cabinet widths/depth references. The document provides the dimensional baseline referenced by subsequent parts of the IEC/EN 60297‑3 series.

General information

• Status: Published / national adoption of the EN text (BS adoption).
• Publication date: 28 February 2009 (BS publication date).
• Publisher: British Standards Institution (BSI) — as BS EN; original IEC base publication by IEC TC 48/SC 48D.
• ICS / categories: 31.240 — Mechanical structures for electronic equipment.
• Edition / version: BS EN 60297-3-100:2009 (identical in technical content to IEC 60297-3-100:2008, Edition 1.0).
• Number of pages: National PDF/print formats commonly listed as 20 pages for the BS edition (national pagination can vary by publisher; the IEC base publication lists 29 pages).

Scope

Defines the basic mechanical dimensions and mounting interfaces for the 482.6 mm (19 in) equipment series: front panels (unit heights and mounting hole positions), subracks and chassis interfaces, rack vertical member and mounting grid arrangements, and basic cabinet types/dimensions. It provides the dimensional baseline that other parts of the IEC/EN 60297‑3 series use for more detailed component and subrack specifications.

Key topics and requirements

• Standard front panel heights and pitch (RU/U conventions, e.g., 1U = 44.45 mm) and tabulated panel dimensions.
• Front‑panel mounting‑hole types and standardised hole positions to ensure interchangeability.
• Definition of rack vertical members, coordination widths and array/adjacency rules for racks.
• Rack/cabinet mounting grid types (Type I and Type II) and guidance on how grid holes align with front panels and subracks.
• Baseline cabinet type descriptions (type A/type B) with reference dimensions for width, depth and plinth/base considerations.
• Terminology and reference to related IEC norms (modular order, electromechanical vocabulary) used as normative references.

Typical use and users

Used by mechanical and hardware engineers, product designers, rack and cabinet manufacturers, OEMs, telecom and data‑centre integrators, installers and procurement teams to ensure physical interoperability of 19‑inch equipment. Typical applications include subrack/chassis design, rack/cabinet manufacture, equipment procurement checks, CAD layout and system integration planning.

FAQ

Q: What is this standard?

A: BS EN 60297‑3‑100:2009 is the British adoption of the EN/IEC standard that defines the basic mechanical dimensions and mounting interfaces for equipment built to the 482.6 mm (19 in) series.

Q: What does it cover?

A: It covers front panel heights and mounting hole positions, subrack and chassis interfaces, rack vertical member layouts and mounting grid types, and baseline cabinet dimensions — providing the dimensional baseline used by other parts of the IEC/EN 60297‑3 series.

Q: Who typically uses it?

A: Mechanical/hardware engineers, rack and cabinet manufacturers, OEMs, system integrators, data‑centre designers and procurement/installation teams who need to ensure physical compatibility across 19‑inch equipment.

Q: Is it current or superseded?

A: The technical base is IEC 60297‑3‑100:2008 (Edition 1.0); the BS EN adoption was published in 2009. The IEC record shows the base publication as the 2008 edition and indicates stability into the 2020s; national page counts and layout vary by publisher. For formal currency and any later amendments or revisions consult the national standards body (BSI) or the IEC catalogue.

Q: Is it part of a series?

A: Yes — it is Part 3‑100 of the IEC/EN 60297‑3 series (mechanical structures for electronic equipment, 482.6 mm / 19 in series); additional parts provide more detailed dimensions for subracks, chassis types and ruggedised (R‑type) variants.

Q: What are the key keywords?

A: 19‑inch, 482.6 mm, 1U, RU, front panel, mounting grid, subrack, chassis, rack, cabinet, IEC 60297, EN 60297, BS EN.
